STUDIES IN TROPICAL TERATOLOGY 
BY 
Dr. J. C. COSTERUS and Dr. J. J. SMITH 
Dr. J. C. COSTERUS, 
The studies now presented are to be considered as a con- 
tinuation of the papers which from 1895 till 1915 we published 
at intervals in these ,Annales’”. For five years circumstances — 
prevented us from co-operating in this way. Nevertheless Mr. 
Smith has remained watchful and active not only in preserving 
all interesting material that came to hand but also by en- 
couraging the East Indian botanists, planters and amateurs to 
do the same and to add their findings to his own. Grateful for 
their support we register their names in alphabetical order:
